Description

Technical Field

[0001] The utility model relates to a plastic equidistant cutting device. Background Art

[0002] In the plastic processing and manufacturing industry, accurate material cutting is one of the key links to ensure product quality and production efficiency. Traditional manual cutting methods are not only inefficient, but also difficult to ensure cutting accuracy. Especially when a large number of repetitive operations are required, it is easy to cause inconsistent cutting sizes, affecting the matching degree of subsequent processing steps and the quality of the final product. Therefore, the market demand for automated, high-precision cutting equipment is growing.

[0003] Early automatic cutting devices mostly used simple linear motion mechanisms, such as electric push rods to drive the cutter to move along a fixed track to achieve straight-line cutting. Although such devices increase cutting speed, when dealing with complex shapes or specific lengths of plastic products that require equidistant cutting, adjusting the cutting spacing is often cumbersome, lacks flexibility, and has limited adjustment accuracy. In addition, they may not be able to adapt well to changes in material thickness, affecting the stability of the cutting effect.

[0004] In response to the above problems, cutting devices with limit adjustment functions have gradually appeared on the market, but these devices are usually complex in structure and have high maintenance costs. In actual operation, the adjustment process may be time-consuming and require professional operation, which reduces production efficiency.

[0005] Therefore, it is particularly important to develop a plastic equidistant cutting device that can not only ensure cutting accuracy but also adjust the cutting distance conveniently and quickly to meet the processing needs of materials of different sizes. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] The pitch adjustment mechanism includes a crank arm 6, a baffle 7 fixed on one end of the crank arm, a screw rod 8 and a guide rod 9 arranged on the other end of the crank arm, a movable hole 10 movably connected to the screw rod and a guide hole 11 movably matched with the guide rod are provided on the end of the rocker, a spring step 12 is provided on the end of the guide rod, a compression spring 13 is sleeved on the guide rod between the spring step 12 and the rocker, and the screw rod passes through the movable hole and is locked by a nut 14.

[0030] In the above technical solution, the distance between the baffle and the cutter can be adjusted by providing a distance adjustment mechanism, so that materials of different lengths can be cut.

[0031] The principle of use is: in the process of loosening the nut, the baffle will naturally force the baffle to slide away from the cutter under the elastic force of the compression spring, thereby increasing the distance between the cutter and the baffle and increasing the cutting length. On the contrary, in the process of locking the nut, the cutting length can be reduced. The entire adjustment method only requires operating the nut, which is simple and convenient to operate.

[0032] Specifically, the guide rod is an equilateral hexagon.

[0033] The guide rod adopts an equilateral hexagonal design, which enhances the guidance and stability between the guide hole, reduces shaking and wear during movement, and further improves the cutting accuracy and service life of the equipment.

[0035] The driving mechanism includes a combination of a driving motor and a reducer, which is connected to the eccentric wheel through the output end of the reducer. It can not only provide a stable driving force, but also realize reasonable control of the cutting speed, optimize the power transmission efficiency, reduce energy consumption, and ensure the smoothness of the cutting action.

[0036] Specifically, an abutment plate 17 is provided on one end of the seesaw away from the cutter, and a roller 18 is provided in a wheel groove below the abutment plate, and the roller abuts against the eccentric wheel.

[0037] An abutment plate and a roller structure are added to one end of the seesaw away from the cutter, so that the contact between the seesaw and the eccentric wheel is smoother, friction and vibration are reduced, and the running stability and durability of the whole system are improved.

[0038] Specifically, a limiting baffle 19 is provided on one side of the material guide plate.

[0039] A limit baffle is added on one side of the material guide plate, which effectively regulates the feeding position of the material, avoids cutting deviation caused by improper material placement, ensures cutting accuracy, and improves the consistency of cutting quality.

[0040] Specifically, a hopper plate 20 is provided on the bracket below the cutter, and side plates 21 are provided on both sides of the hopper plate.

[0041] The inclined hopper plate and side plates under the cutter optimize the collection and unloading process of the cut products, reduce the risk of material accumulation and blockage, improve work efficiency, and facilitate subsequent material processing and sorting.

[0042] Specifically, a column 22 is provided on the frame, and a rotating shaft 23 is provided on the column. The rotating shaft is rotatably connected to the seesaw through a bearing.
